Show downwards arrow on SelectButton (#1521)
* Show downwards arrow on SelectButton

The arrow wasn't showing because the button linear-gradient background overrides the background-image for the arrow.

Select can't have pseudo-elements, so I had to add an extra div.

* Remove height definition

to fix text cutting off on Windows.

* Hide default arrow in light theme

to keep consistency with dark theme, where the arrow has to be custom due to the button gradient.

* Use alternative approach to prevent text getting cropped

and add height definition back again.

* Adjust arrow position for rtl
